i i sure having a high value which would ini Y energy of the fluid. The device embodying terfere with the proper utilization of the the invention, effects this diminution in volume by canalizing the exhaust gases of the "turbine in tubes located in a compartment of the torpedo, accessible from the waterv The gases being strongly cooled by passing through the tubes which act as a n kindfof surface condensers, they are recovered in a fluid-tight compartment communicating with the hollow tube controlling the propellers,through which the said gases are exhausted in the known manner.

According to the invention, the fluid-tight compartment wherein the tubes acting as condensers, open, is provided with a pump {intended to expel the condensedproducts I of the motive fluid. Finally, in the case where it. is necessary to impart an impulse to the motive .fiuid, cooled in the manner hereinbefore described, through the inner end of the concentric shafts controlling the propellers, the motive fluid tube condensers 1 those hitherto in use. The cooling elewill assume the shape of coils with a view to elongating the path of this fluid in the cooling medium. i

' This device has considerable advantages mentof which use is made, has an infinite capacity and its circulation is insured without the least'expenditure in energy. .Morej. over, the canalization of thehotgases at .their outlet, in fluid-tight compartments, permits of obviating the deterioratingeffeet they have on the members with which This shaftis driven Specification of Letters Patent.

When the torpedo is submerged, water entering through the orifices N invadesthe compartment Kand surrounds the pipes I. It will be readily understood that the motive fluid is subjected to an energetic cooling action inside these tubes.

The cooled fluid penetrates subsequently a fluid-tight compartment P and is drawn in by a bladed wheel R integral with the driving shaft, which forces'the said fluid into the hollow shaft G. for exhausting in a rearward direction. A pump Q drawing in at the lower part of the reservoir, rejects externally the condensed products; it may be readily controlledby means of an eccentric keyed on the driving shaft.
